So today’s issue was a slow server reported at 4pm today, it was still working but accessing and saving files was taking a long time and redirected folders weren’t working.

Instant response after phone call. Remote diag took 30 mins, but the issue got worse and remote tools stopped connecting. Onsite by 5:20pm. Server showing same issues at the console when stood in front of it.

Attempted soft restart which didn’t work. Hard reboot performed and server up and running by 6pm ready for the clients team coming in tomorrow.

Diag as to underlying issue will continue tomorrow AM, but suspected Windows Update failed reboot was the cause.
